Hi Ajay,
The Virtual Service Response Time metrics should help you.
Virtual Service Metrics Reports - DevTest Solutions - 10.1 - CA Technologies Documentation
"The Virtual Service Response Time report displays the displays the maximum, average, and minimum response times, in milliseconds, in the form of a line graph. The response times are captured according to a defined sampling interval. Each data sample is represented by a square block on the report. The sampling interval defaults to every 5 minutes, but you can modify the interval by setting the lisa.vse.metrics.sample.interval property in your local or site properties file"

The properties below control how often old metric data is scanned for and deleted, and what is considered old.
lisa.vse.metrics.delete.cycle=1h
lisa.vse.metrics.delete.age=30d
Hope it helps.
